The cycle of learning

When has learning taken place? This is quite a complicated question and will depend among other things on how the new knowledge or skill will be used. One thing that is certain is that for the purposes of learning an instrument we should aspire to a deep multidimensional learning that we can draw on instantly and that becomes part of our musical vocabulary. In other words we need the skill and knowledge to be pliable, adaptable, and deeply memorised. To achieve this level of learning I recommend you go through the following 'cycle of learning' on all exercises and songs you learn.

Learn to play the exercise (or lick, riff, solo, song etc..) breaking it up into smaller chunks if need be

Play it while tapping your foot in time

Play it with a metronome

Memorise it

Play it in different tempos (intermediate/advanced)

Play it in different keys/places on the guitar (intermediate/advanced)
